We posted the full session on X <a href=\"https:\/\/x.com\/OntologyNetwork\/status\/1984153694464831541\">here<\/a>. If you missed it, this summary gives you the practical habits to use Web3 with more confidence.<\/p>\n\n\n\n<p>Note: The information below is for education only. It describes options, questions, and factors to consider.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Web3 security foundations<\/h2>\n\n\n\n<p><strong>Blockchain in one sentence:<\/strong> a public ledger where many computers agree on the same list of transactions.<br><strong>Private key:<\/strong> the secret that lets you move your coins. Whoever controls it controls the funds.<br><strong>Self custody vs custodial:<\/strong> self custody means you hold the keys. Custodial means a platform holds them for you.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Choosing venues: exchanges and custodians<\/h2>\n\n\n\n<p><strong><em>What people usually try to learn about a venue<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>How customer assets are held and whether segregation is documented<\/li>\n\n\n\n<li>Whether the venue publishes proof of reserves and whether liabilities are discussed<\/li>\n\n\n\n<li>What governance or policy controls exist for large transfers<\/li>\n\n\n\n<li>How compliance, KYC\/AML, and audits are described<\/li>\n\n\n\n<li>Incident history and the clarity of post-incident communications<\/li>\n\n\n\n<li>Withdrawal behavior during periods of stress<\/li>\n<\/ul>\n\n\n\n<p><strong><em>Common storage language<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hot storage: internet-connected and convenient<\/li>\n\n\n\n<li>Cold storage: offline and aimed at reducing online attack surface<\/li>\n<\/ul>\n\n\n\n<p><br>Trading and custody involve process and oversight. Public signals such as disclosures, status pages, and audit summaries help readers form their own view of venue risk.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Bridge security: moving across chains safely<\/h2>\n\n\n\n<p>Think of bridges as corridors, not parking lots. A bridge locks or escrows assets on one chain and represents them on another. Because value crosses systems, bridges can be complex and high-value points in the flow.<\/p>\n\n\n\n<p><strong><em>Typical points to check or ask about<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Official interface and domain<\/li>\n\n\n\n<li>Current status or incident notes published by the team<\/li>\n\n\n\n<li>Fee estimates and expected timing<\/li>\n\n\n\n<li>Any approvals a wallet is about to grant and to which contract<\/li>\n\n\n\n<li>Whether a small \u201ctest\u201d transfer is supported and how it is verified<\/li>\n\n\n\n<li>How the project communicates delays or stuck transfers<\/li>\n\n\n\n<li>Whether there is a public pause or circuit-breaker policy<\/li>\n<\/ul>\n\n\n\n<p><strong><em>Terms that appear in bridge discussions<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Validator and quorum or multisig: several independent signers must approve sensitive actions<\/li>\n\n\n\n<li>Reentrancy: a contract is triggered again before it finishes updating state<\/li>\n\n\n\n<li>Toolchain: compilers and languages a contract depends on; versions and advisories matter<\/li>\n<\/ul>\n\n\n\n<p><br>Movement across chains touches multiple systems at once. Understanding interfaces, messages, and approvals can help readers evaluate their own tolerance for operational complexity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Stablecoins: reserves, design, and plans<\/h2>\n\n\n\n<p><strong><em>What a \u201cdollar on-chain\u201d can be backed by<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Cash and short-term treasuries at named institutions<\/li>\n\n\n\n<li>Crypto collateral with over-collateralization rules<\/li>\n\n\n\n<li>Algorithmic or hybrid mechanisms<\/li>\n<\/ul>\n\n\n\n<p><strong><em>Questions readers often ask themselves<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>What assets back the stablecoin and where are they held<\/li>\n\n\n\n<li>How concentration across banks, issuers, or designs is handled<\/li>\n\n\n\n<li>What signals would trigger a partial swap or a wait-and-see approach<\/li>\n\n\n\n<li>Which sources are monitored for updates during stress<\/li>\n<\/ul>\n\n\n\n<p><strong><em>Example elements of a personal depeg plan<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Signals: price levels or time thresholds that prompt a review<\/li>\n\n\n\n<li>Actions: small, incremental adjustments rather than all-or-nothing moves<\/li>\n\n\n\n<li>Sources: issuer notices, status pages, and established news outlets<\/li>\n<\/ul>\n\n\n\n<p><br>Designs behave differently under stress. Defining personal signals and information sources ahead of time can make decisions more methodical.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Human layer protection: phishing, privacy, browser hygiene<\/h2>\n\n\n\n<p><strong><em>Patterns commonly seen in phishing or social engineering<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Urgency or exclusivity, requests to \u201cverify\u201d a wallet, surprise airdrops<\/li>\n\n\n\n<li>Lookalike domains, QR codes from unknown accounts, unsigned or opaque transactions<\/li>\n\n\n\n<li>Requests for seed phrases or private keys (legitimate support does not request these)<\/li>\n<\/ul>\n\n\n\n<p><strong><em>Privacy points that often come up<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use of a work or pickup address for hardware deliveries<\/li>\n\n\n\n<li>Awareness that marketing databases can leak personal details<\/li>\n<\/ul>\n\n\n\n<p><strong><em>Browser and device considerations people weigh<\/em><\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A separate browser profile for web3 use with minimal extensions<\/li>\n\n\n\n<li>Regular device and wallet firmware updates<\/li>\n\n\n\n<li>For shared funds, whether a multisig or policy-based account would add useful checks<\/li>\n<\/ul>\n\n\n\n<p><br>Many losses begin with human interaction rather than code. Recognizing common patterns can help readers evaluate messages and prompts more calmly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Web3 security glossary<\/h2>\n\n\n\n<p><strong>Bridge:<\/strong> locks an asset on chain A and issues a representation on chain B<br><strong>Wrapped token:<\/strong> an IOU on one chain representing an asset on another<br><strong>Oracle:<\/strong> external data or price feed for smart contracts<br><strong>Reentrancy:<\/strong> re entering a contract before the state updates which can enable over withdrawal<br><strong>Multisig or quorum:<\/strong> multiple keys must sign before funds move<br><strong>Proof of reserves:<\/strong> an attestation that holdings cover obligations and is meaningful only if it includes liabilities<br><strong>Self custody: <\/strong>you hold the private keys which brings more responsibility and less venue risk<br><strong>Cold storage:<\/strong> offline key storage that is safer from online attack<br><strong>KYC or AML:<\/strong> identity and anti money laundering controls<br><strong>Seed phrase:<\/strong> the words that are your wallet.
